Cervical spinal stenosis includes both primary and secondary. Bone structure hyperplasia, disc herniation, and ossification of ligaments in the spinal canal can lead to changes in the intervertebral foramina, such as narrowing of the intervertebral foramina, narrowing of the intervertebral space, and even disc herniation or bulging, which protrudes into the spinal canal and leads to a decrease in the transverse and sagittal diameters of the spinal canal or a decrease in the overall volume of the spinal canal, which can lead to compression of the nerves, spinal cord, and impaired blood flow to the nerves and the spinal cord, leading to neurological deficits. The symptoms are secondary to cervical spinal stenosis.
